The proposed design is a four-section, three-man boat with load capacity of 320 kg In tourist trips she, being dragged to the Bank, turns in a fairly spacious “tent”, especially if you throw on top of a piece of plastic film. The boat is so simple that it can make even a person unfamiliar with shipbuilding and have only basic skills working with wood. To manufacture do not need special equipment and space, the whole boat is going in the room of a city apartment. It is made from widely available materials that can be Purchased in stores construction And household goods. The cost is Approximately 20-30 rubles (in passing it should be noted that for the registration of boats is necessary to keep all checks and receipts).

Kordovye aircraft models — the most popular among modelers. First among them is “air fighters”. And it is clear. The airfield may be a stadium, any forest or meadow flat area with a diameter of 40-50 m. One of the main requirements for such models, the simplicity of manufacture. Indeed, during the “air battle” inevitable collision and, consequently, breakdowns.
Siberian airfields early 70-ies of the last century — the time of intensive development of the Tyumen oil fields — is hard to imagine without helicopters, created in OKB M. L. Mil. In the summer the airfield is a small airport in Surgut worked several hundred helicopters. In addition to local squadron here flew helicopters from all over the Soviet Union. Mi-2, Mi-4, Mi-6 and Mi-8 was raised to the sky during the long daylight hours. Mi-2 and Mi-4 was delivered to the place of work of geologists, drillers, and numerous teams of builders, heavy Mi-6 was carrying bricks, boards, barrels of fuel, pipe, power transmission towers, drilling equipment, mobile homes. Such intense and dedicated work is clearly confirmed, as required in terms of the local offroad helicopter.
As you know, four-wheel drive Jeep Wrangler are derived from army vehicles to Willis MB and Ford GP. They inherited from prototypes, high reliability, Spartan simplicity and ruggedness.

When repairing machinery, especially agricultural, are quite common and at the same time melomakarouna operations cutting of sheet iron, and the manufacture of cardboard strips with holes. Often these works are performed with hand tools that does not provide neither the productivity nor quality.
The proposed device allows you to charge any rechargeable batteries with voltage from 1.2 to 15 V and a nominal capacity of from 0.05 to 20 A·h and can be widely used in radio, car owners and even users of electronic equipment. The device is a charger (current stabilizer), which uses a pulse-frequency regulation, which eliminates the need for bulky heat sink from the control transistor.
